To all whom it may concern:

Be it known that l', BERNIIA'RD lnonmns, engineer, subject of Sweden, residin at Torvegade No. 50, Copenhagen, in the i in dom of Denmark, have ini enled new an useful Improvements in Centrif ugal Se waters, of which the following is a speci cation.

L'entrifu ul drums or apparatus are alread well Known in which mill: passes up wnr ly from a centrally urrunged milk inlet chamber into distributing pipes and thence through openings in the SIdBS of: the pipes to the spaces between the liner plates. In these drums the distrihutingpipes are gen 'erally made integral with the central sup ply pipe of the drum, through which pipe the milk is conveyed to the central clnnnl icrv Thisconstruction of the distributing;- derive renders it however diilivnli to lit the sepu rate parts of the drum together, and fur her the fact that dish-flaming pipes are closed at the to makes it exceedingly d iili cult to clean t 1e pipes. Fnrthernun'c the openings in the sides of the known CllSi-I'lliuting pipes are situated at the points having the greatest distance fromillo control axis of the drum, an nrrnngi-nwnl which however has been found to he in adequate, hecnuse the milk flowing onl of lho openings is not distributed equally over the liner plates.

According to the present im'vnlion the distributing pipes are 'orn'ied by n loose rcmovably inserted on and fil'tihp;

c-usinlg ,closey around the central supply pipe and -hav1ng in its lower portion :1 number separate inwardly open hollow channels communicating at their bottom with the central chamber and communicating with the spaces between the liner plates through openings, which seen in the'dircction of retation of the drum are situated close behind those points of the casin which haf've the greatest distance from t e central axis of the drum. By such an arrangement the distributing device can be easily cleaned as the channels, when the loose casing isremoved from the central pipe, lie fully open for inspection and cleanin furthermore the de-- scribed location of t e openings secures an p ates.

equal distribution of the milk over the liner.

l'he holirjnn pm-iion a of the drum to which is secured the spindle b integral with the pipe r: which isiirrnnged in the center of the drum and provided at the bottom with mltletfopcnings a, ll'irough which the milk introilncif-d from the top into the pipe escapes into the chamber a at [he lower part of (he rlrnnr Al tlntop, the pipe is proided wi h an exterior srreiw-tliread and with 1| nni. f. wherein the casing g of the drum ls son-mod in tho bottom portion'u in well known nmnncr.

A cliatrilnding: mp or easing/r. is arranged around lhc c'cnirzil pipe 0; its cross-section, as shown in Fig. is slur shaped, so that :1. number of separate inwardly open hollow iar-e ections uirc jirodnccd. L-iose behind the )oinls of llH hollow ii-ejections, which seen 1n the dirorl i n ol' roinlion of the drum (sec llie arrow l 'i 1) ha vo the greatest distance from the rcnlrnl axis of the druni, are ar which the milk is dislrihntoxl lo the spores hctw n the liner plates. The cup 12. iits lightly around. the pipe rr. at the top so Hot a number of dislributing channels corresponding to the projections oi the cup are produced. These distributing; ehnnncls are closed at the top, and their inner surface is formed by the outer wall of the cenirnl pipe r, while the rejections of the cup form the outer surace of the clnmi'iels, and the channels are sen-ruled from our-h other by the portions 0 the ca Ii. which contact with the central pipe 0. llhe distributing! channels I which at the bottom open into the chamber 0 have the some notion as the well known pipes, hutthey can be easily clc ed, as, after the nut f and the drum cirsin, are removed, the cop It can be taken out and cleaned on the inside. In this way, the pipe (.2 and the interior of the chamber are made accessible and can also be easily cleaned. After clean ing, the [parts can be eosil fitted together again an the nut f can be tightened.

the central supply of Lhcloose distrihuttil) Having thus described the invention, what I claim and desire to secure by Letters Patcnt is: i In a centrifugal machine the combination 5 with a drum having a central chamber at its 1 bottom and having a number of liner plates i and provided with a central inlet pipe I through which the liquid is introduced into i the central chamber of a loose casing removably inserted on and fitting closely around the inlet-pipe and having in its lower ortion a numberlof separate inwardly open oilow channels communicating at their botton-i with the central chamber and communieating with the spaces between the liner plates through openings, which seen in the direction of rotation of the drum are situated close behind those points of the casing, which have the greatest distance from the central axis of the drum.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
